[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] As attached Figure 1-3 The T-shaped knife for processing a thin slice shown in the figure comprises a handle 1, a blade 2 is installed on the upper end of the handle 1, and the blade 2 is provided with four teeth, and the four teeth are staggered, wherein two teeth are arranged at the front end of the blade 2, and the other two teeth are arranged at the rear end of the blade 2, and the two teeth arranged at the front end of the blade 2 are staggered with the two teeth arranged at the rear end of the blade 2, the two teeth arranged at the front end of the blade 2 are used to process the bottom surface and the end surface of the thin slice, and the two teeth arranged at the rear end of the blade 2 are used to process the top surface of the thin slice, and the blade 2 includes a handle 1 for connecting to the handle 1 A connector 201, wherein two first teeth 202 for processing the top surface of the slice are arranged at the bottom end of the connector 201, and two second teeth 203 for processing the bottom surface and the end surface of the slice are arranged at the bottom end of the two first teeth 202, the two first teeth 202 are two teeth arranged at the rear end of the blade 2, and the two second teeth 203 are two teeth arranged at the front end of the blade 2, and a spiral groove 204 is opened between each of the teeth, the front angle of the second tooth 203 is 3°, the back angle is 10°, and the axial angle is 5°, and the spiral angle of the spiral groove 204 is 30°.

[0018] In specific implementation, the second tooth 203 is attached to the bottom and end surface of the slice, and the first tooth 202 is attached to the top surface of the slice. During processing, the upper and lower surfaces and the end surface are processed synchronously, so that the two surfaces are subjected to force at the same time to reduce deformation, thereby reducing the vibration between the blade 2 and the slice, and forming an integral part, thereby improving processing efficiency and processing yield. During the processing, the generated debris flies out along the spiral groove 204, thereby avoiding the debris from accumulating on the blade 2, thereby avoiding the debris from affecting the processing, further improving the yield, and at the same time, it also avoids the situation where the high temperature generated during processing causes the debris to melt and adhere to the blade 2 or the slice.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
